The Barrett M107 Long Range Sniper Rifle is a .50 BMG, semi-automatic sniper rifle utilized by the United States Army in the early 2000s.

This weapon is also sold as the Barret M107 commercially to the qualified general public. It is a new designation of the prominent M82 Special Applications Scoped Rifle (which has also been commercially available for qualified individuals from Barrett as the M82 series) in the United States military. The M107 is used for conventional and traditional sniper tasks, but is especially useful for counter sniper, long range and anti materiel situations over more traditional smaller bore sniper rifles.

There are no distinct differences between the Barrett M82A1M / M82A3 and the M107. However, there are rumors of internal improvements and production M107s appear to have the addition of a rear monopod. The actual information has not been widely available.

In 2005 the M107 was voted Top 10 Military Inventions by the U.S. Army
